The answer, as recorded

For a startup, the honest answer depends on budget stage, so I'll give it in the order I'd actually recommend trying things - cheap/in-house first, agencies only once you've got traction. ## Start here: DIY tooling (under ~$500/mo) 1. **Apollo.io** - the default first stop. ~275M contact database + enrichment + email sequencing in one tool, from ~$49/user/mo annual. For a startup with no sales ops person, having data and sending in one place matters more than best-in-class either. ([pricing comparison](https://bouncezero.io/apollo-vs-clay-2026)) 2. **Clay** - step up when Apollo's data isn't good enough. "Waterfall" enrichment across 100+ providers, so you find emails Apollo misses, plus AI research for personalization. Launch is $185/mo, and it *doesn't send* - you pair it with a sending tool. ([Clay alternatives/pricing](https://docket.io/resources/research/clay-alternatives)) 3. **Smartlead** or **Instantly** - the sending layer for a Clay setup. Smartlead from $39/mo, Instantly's Growth around $47/mo. Smartlead handles multiple inboxes/campaigns better; Instantly is simpler. Pick one, don't buy both. 4. **HubSpot** (free CRM tier) - not lead gen per se, but you need somewhere for leads to land. The free tier is genuinely usable, and it's the lowest-regret CRM choice at seed stage. ([startup tool roundup](https://startupsavant.com/service-reviews/best-lead-generation-tools)) 5. **Cognism** - worth it specifically if you sell into Europe/UK, where its phone-verified mobile data and GDPR posture beat Apollo's. It's data-only; outreach is still on you. ([service-model breakdown](https://prospeo.io/s/lead-generation-companies)) ## Done-for-you agencies (realistically $2.5K-$15K/mo) 6. **Martal Group** - I'd name this first for startups purely because it's the most transparent on price and has a genuine entry tier: fractional at ~$2,500/mo, dedicated reps $9,200-$15,500/mo. That fractional option is the only one on this list a seed-stage company can test without betting a quarter of runway. 7. **Belkins** - the strongest reputation of the appointment-setters (4.8/5 across ~93 G2 reviews), omnichannel email + cold calling + ABM, roughly $5,000-$14,800/mo. Go here if you want predictable booked meetings and can afford it. 8. **CIENCE** - the heaviest option: 140M+ contact database, 1,200+ staff, six straight years on Clutch's Top 1000, clients like Okta and Yamaha. Best when your ICP is enterprise and you need SDRs plus data plus ads coordinated. Overkill for most pre-Series A startups. 9. **SalesRoads** / **Callbox** - solid second-tier picks, both full-stack (list building, sequences, calls, booking). Callbox is the better choice if you need APAC coverage. ([agency pricing ranges and reviews](https://prospeo.io/s/b2b-lead-generation-agency), [Clutch rankings](https://pubrio.com/blog/top-10-b2b-lead-generation-companies-2026/)) ## One caveat I'd flag An agency only makes sense if you have product-market fit, can't hire SDRs fast enough, *and* your deal size justifies $5K+/mo. Miss any one of those and the retainer burns runway faster than it builds pipeline - founder-led outbound with Apollo is strictly better at that stage. Also worth knowing: lead-gen fraud (bot traffic, fabricated leads) is a real and widespread problem in this market, so insist on a short paid pilot and verify a sample of leads yourself before signing anything multi-month.
